| TJAP1

Tight junction-associated protein 1 is a protein that is encoded by the TJAP1 gene.TJAP1 has been shown to interact with DLG1.This gene encodes a tight junction-associated protein. Incorporation of the encoded protein into tight junctions occurs at a late stage of formation of the junctions. The encoded protein localizes to the Golgi and may function in vesicle trafficking. Alternatively spliced transcript variants have been described. A related pseudogene exists on the X chromosome.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (pg/mL)	5000	2500	1250	625	312	156	78	0
OD	2.28	1.45	0.84	0.5	0.33	0.24	0.18	0.08
Corrected OD	2.2	1.37	0.76	0.42	0.25	0.16	0.1	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Rat TJAP1 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	83-101	96
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	97-108	103

 

| Linearity

Samples were spiked with high concentrations of Rat TJAP1 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	86-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	110
